Front Riser Down Position Stuck
NOTE:
After making any repairs, perform MEMORY SYSTEM VERIFICATION TEST under VERIFICATION TESTS.
- Using scan tool, erase DTCs from Memory Seat/Mirror Module (MSMM). Operate driver's power seat and memory functions. Turn ignition off. Start engine and let idle for approximately one minute. Recheck for DTCs in MSMM. If FRONT RISER DOWN POSITION STUCK resets, go to next step. If FRONT RISER DOWN POSITION STUCK does not reset, conditions necessary to set this DTC are not present at this time. Check for intermittent poor connections or faulty circuits and repair as necessary. See POWER SEATS in appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL.
- Disconnect power seat switch connector. Using DVOM, measure voltage between ground and power seat switch connector terminal No. 10 (Light Green/Tan wire). See Fig 1. If any voltage is present, go to next step. If no voltage is present, replace power seat switch.
- With DVOM still connected, locate and disconnect MSMM connectors. See COMPONENT LOCATIONS . Turn ignition on. If no voltage is present, replace MSMM. See MEMORY SEAT/MIRROR MODULE under REMOVAL & INSTALLATION. If any voltage is present, repair short to voltage in Light Green/Tan wire between MSMM connector C2 terminal No. 8 and power seat switch. See Figure and Figure .
